During the recent total solar eclipse in the US, I overlapped my hands, using the gaps between my fingers to form "pinholes". Just before the start of totality, someone noticed that the shadows formed through this "pinhole camera" onto a whiteboard were so sharp that the individual hairs on my arms were visible.
